Background:
Epiploic appendagitis is an ischemic infarction of an epiploic appendage caused by torsion or spontaneous thrombosis of the central draining vein. Epiploic appendagitis is self-limited without surgery, and it is imperative for clinicians to be familiar with this entity.
Case Report:
A healthy 27-year-old man was admitted due to acute right lower quadrant abdominal pain. Physical examination showed focal abdominal tenderness with slight rebound tenderness. Laboratory tests showed leukocytosis and an increased serum C-reactive protein level. Computed tomography (CT) showed a fatty ovoid pericolonic mass measuring 12 mm in diameter, with a circumferential hyperdense ring that abutted on the ascending colon and was surrounded by ill-defined fat stranding with a hyperdense ring. These findings were diagnostic of primary epiploic appendagitis. The patient was given high-dose antibiotics due to the secondary inflammation involving the parietal peritoneum.
Conclusions:
Epiploic appendagitis presents with an abrupt onset of focal abdominal pain and tenderness without significant guarding or rigidity; it is an uncommon and difficult diagnosis. With awareness of this condition, however, evaluation by CT can provide an accurate diagnosis of epiploic appendagitis, distinguishing it from conditions with clinically overlapping manifestations.
Insights
Epiploic appendagitis, an uncommon cause of abdominal pain, involves ischemic infarction of an epiploic appendage. Computed tomography (CT) is crucial for accurate diagnosis, differentiating it from other conditions.
Area of Science:
- Gastroenterology
- Abdominal Imaging
Background:
- Epiploic appendagitis is a self-limiting condition caused by ischemic infarction of an epiploic appendage.
- It results from torsion or spontaneous thrombosis of the appendage's central draining vein.
Observation:
- A case report details a 27-year-old male presenting with acute right lower quadrant abdominal pain.
- Physical examination revealed focal tenderness, and laboratory tests showed leukocytosis and elevated C-reactive protein.
- Computed tomography (CT) identified a characteristic pericolonic mass with a hyperdense ring and surrounding fat stranding.
Findings:
- CT findings were diagnostic of primary epiploic appendagitis.
- The patient received antibiotics due to secondary parietal peritoneum inflammation.
Implications:
- Epiploic appendagitis presents with sudden focal abdominal pain and tenderness.
- Accurate diagnosis is challenging but achievable with CT, distinguishing it from conditions with similar symptoms.
- Clinical awareness of epiploic appendagitis is essential for appropriate patient management.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
